i've thought about this a lot... wanting to understand where it came from. I have several very early memories, kindergarden or younger.
I was very aware that I had a big round tummy very young. We had a girl my age a few houses down and we'd play together and often we'd compare our tummies and mine was always so much bigger and stuck out more. I was kinda fascinated by it, how big it was, rubbing it, eating, filling it.
I know I liked feeling full... I remember sitting at the table, I think possibly still in a high chair and asking for more food because "I want more in my tummy...My tummy wants more" or something. The grownups all laughed I remember that.
And another very early memory: my grandfather was very fat and a big eater. Tiny me tried to eat as much as he did... i can hear his low rumbly laugh as he jokingly egged me on... and i can still see his big belly shaking as he laughed, and how enormously full I felt.
I also have distinct memories of stuffing a pillow in my shirt or my pyjama onesie from like 3-4 or so... in my cot while napping after lunch. I remember it felt so comforting to have a full stomach and then my huge pillow-belly to hug.
I also figured out very early that if i used elastic but robust materials I could recreate the kind of pressure I felt when I overate, I had this one fairy or mermaid leotard thing for dress-up and it was very shiny and very stretchy but also extremely resistant to force.
I would put on that leotard over a very thick and fluffy sweater that i'd stuffed more clothes under and oooooh the compression on my big tummy felt so good, and also how enormous it looked... I'd waddle around my room, arching my back, sticking my tummy out as far as it went and rub my hands all over it's shiny smooth roundness.
And then later came the books and stuff I just obsessed over. that part in Matilda, with the chocolate cake...
